        <h1 id="1、简介"><a href="#1、简介" class="headerlink" title="1、简介"></a>1、简介</h1><p>Laravel Excel 在 Laravel 5 中集成 PHPOffice 套件中的 PHPExcel ，从而方便我们以优雅的、富有表现力的代码实现Excel/CSV文件的导入和 导出 。<br>该项目的GitHub地址是： <a href="https://github.com/Maatwebsite/Laravel-Excel" target="_blank" rel="external">https://github.com/Maatwebsite/Laravel-Excel</a> 。<br>本文我们将在Laravel中使用Laravel Excel简单实现Excel文件的导入和导出</p>
<h1 id="2、安装-amp-配置"><a href="#2、安装-amp-配置" class="headerlink" title="2、安装&amp;配置"></a>2、安装&amp;配置</h1><p>使用Composer安装依赖<br>首先在Laravel项目根目录下使用Composer安装依赖：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">composer require maatwebsite/excel ~2.0.0</div></pre></td></tr></table></figure>
<p>安装后的设置<br>在 config/app.php 中注册服务提供者到 providers 数组：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">Maatwebsite\Excel\ExcelServiceProvider::class,</div></pre></td></tr></table></figure>
<p>同样在 config/app.php 中注册门面到 aliases 数组：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">&apos;Excel&apos; =&gt; Maatwebsite\Excel\Facades\Excel::class,</div></pre></td></tr></table></figure>
<p>如果想要对Laravel Excel进行更多的自定义配置，执行如下Artisan命令，执行成功后会在 config 目录下生成一个配置文件 excel.php 。</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">php artisan vendor:publish</div></pre></td></tr></table></figure>
<h1 id="3、导出Excel文件"><a href="#3、导出Excel文件" class="headerlink" title="3、导出Excel文件"></a>3、导出Excel文件</h1><p>为了演示Laravel Excel相关功能，我们为本测试创建一个干净的控制器 ExcelController.php ：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">php artisan make:controller ExcelController --plain</div></pre></td></tr></table></figure>
<p>然后在 web.php 中定义相关路由：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div></pre></td><td class="code"><pre><div class="line">$router-&gt;get(&apos;excel/export&apos;,&apos;ExcelController@export&apos;);</div><div class="line">$router-&gt;get(&apos;excel/import&apos;,&apos;ExcelController@import&apos;);</div></pre></td></tr></table></figure>

<p>我们在浏览器中访问 <a href="http://localhost:8000/excel/export" target="_blank" rel="external">http://localhost:8000/excel/export</a> ，会导出一个名为 召回用户黑名单.xls 的Excel文件：</p>
<p><img src="http://oe2qf8as1.bkt.clouddn.com/854F.tm.png" alt="111"></p>
<p>如果你要导出csv或者xlsx文件，只需将 export 方法中的参数改成csv或xlsx即可。<br>如果还要将该Excel文件保存到服务器上，可以使用 store 方法：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div></pre></td><td class="code"><pre><div class="line">Excel::create(&apos;召回用户黑名单&apos;,function($excel) use ($cellData)&#123;</div><div class="line">     $excel-&gt;sheet(&apos;score&apos;, function($sheet) use ($cellData)&#123;</div><div class="line">         $sheet-&gt;rows($cellData);</div><div class="line">     &#125;);</div><div class="line">&#125;)-&gt;store(&apos;xls&apos;)-&gt;export(&apos;xls&apos;);</div></pre></td></tr></table></figure>
<p>文件默认保存到 storage/exports 目录下，如果出现文件名中文乱码，将上述代码文件名做如下修改即可：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">iconv(&apos;UTF-8&apos;, &apos;GBK&apos;, &apos;召回用户黑名单&apos;)</div></pre></td></tr></table></figure>
<h1 id="4、导入Excel文件"><a href="#4、导入Excel文件" class="headerlink" title="4、导入Excel文件"></a>4、导入Excel文件</h1><p>我们将刚才保存到服务器上的Excel文件导入进来，导入很简单，使用 Excel 门面上的 load 方法即可：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div><div class="line">8</div></pre></td><td class="code"><pre><div class="line">Excel文件导入功能  </div><div class="line">public function import()&#123;</div><div class="line">    $filePath = &apos;storage/exports/&apos;.iconv(&apos;UTF-8&apos;, &apos;GBK&apos;, &apos;召回用户黑名单&apos;).&apos;.xls&apos;;</div><div class="line">    Excel::load($filePath, function($reader) &#123;</div><div class="line">        $data = $reader-&gt;all();</div><div class="line">        dd($data);</div><div class="line">    &#125;);</div><div class="line">&#125;</div></pre></td></tr></table></figure>
<p>load 方法基于项目根路径作为根目录，同样我们对中文进行了转码，否则会提示文件不存在。<br>在浏览器中访问 <a href="http://localhost:8000/excel/import" target="_blank" rel="external">http://localhost:8000/excel/import</a> ，页面显示如下：</p>
<p>当然，Laravel Excel还有很多其它功能，比如将Blade视图导出为Excel或CSV，以及对导入/导出更加细粒度的控制，具体可参考其官方文档： <a href="http://www.maatwebsite.nl/laravel-excel/docs" target="_blank" rel="external">http://www.maatwebsite.nl/laravel-excel/docs</a></p>
